What Is an Ostomy? A Complete Guide for Beginners

Finding out that you may need a stoma can bring a lot of questions at once. You might wonder what your body will look like, whether you will still be able to leave the house normally, or how you will manage a stoma bag every day.

If you feel nervous or overwhelmed, you are not alone. Learning the basics can make the unfamiliar feel much more manageable.

So, what is an ostomy, exactly? In simple terms, an ostomy is a surgically created opening on the abdomen that allows waste from the bowel or urinary system to leave the body through a stoma. A pouch or bag is worn over the stoma to collect that waste.

This guide explains the essentials without complicated medical language, so you know what the terms mean and what questions you may want to ask your healthcare team.

What Does Ostomy Mean?

The ostomy meaning can be easier to understand when you think of it as a new route for waste to leave the body.

During ostomy surgery, a surgeon creates an opening through the abdominal wall and brings part of the bowel or urinary system through it. The exposed opening is called a stoma.

Depending on the type of surgery, the stoma allows either faeces or urine to leave the body. A specially designed stoma bag sits over the stoma and collects the output.

An ostomy may be temporary or permanent. Some people need one while their bowel or another part of the digestive system heals, while others require a permanent change because of their underlying condition or surgery.

Why Might Someone Need an Ostomy?

There is no single reason why someone might have ostomy surgery.

Stoma surgery can be part of treatment for conditions affecting the bowel or bladder. These can include bowel cancer, Crohn’s disease, diverticular disease, inflammatory bowel disease, trauma, or other situations where part of the bowel or urinary system needs to be removed, diverted or allowed to rest.

Sometimes surgery is planned in advance. In other situations, an ostomy may be created during emergency surgery.

Your surgeon or stoma nurse can explain exactly why an ostomy is recommended in your individual circumstances.

The Three Main Types of Ostomy

One of the first things beginners encounter is a list of unfamiliar terms. The types of ostomy generally fall into three main categories: colostomy, ileostomy and urostomy.

1. Colostomy

A colostomy is made using part of the large bowel, or colon. The colon is brought through an opening in the abdomen to create the stoma.

Waste then leaves the body through the stoma rather than following its usual route through the bowel. Depending on where the colostomy is formed and how much colon remains, the consistency of the output can vary.

2. Ileostomy

An ileostomy uses the ileum, which is the end of the small intestine.

The end of the small bowel is brought through an opening in the abdomen, creating the stoma. Because the waste has not passed through the large bowel, ileostomy output is often softer or more liquid.

An ileostomy can also be temporary or permanent, depending on the reason for surgery.

3. Urostomy

A urostomy provides a new route for urine to leave the body.

Instead of faeces being collected, urine passes through the stoma into a urostomy pouch. The exact surgical technique varies depending on the person’s condition and the operation they have had.

What Does a Stoma Look and Feel Like?

If you have never seen a stoma before, it can understandably feel strange at first.

A healthy stoma is usually pink or red and moist, somewhat like the inside of your mouth. It can be flat against the skin or extend slightly outward, depending on how it was created.

One important thing to know is that a stoma does not work like an ordinary bowel opening. You cannot normally control exactly when output or wind comes through it, which is why the stoma bag is worn continuously to collect it.

Your stoma nurse will show you what is normal for your particular stoma and help you recognise changes that should be checked.

What Is an Ostomy Bag?

An ostomy bag, often called a stoma bag in the UK, is a pouch attached to the skin around the stoma.

Its purpose is straightforward: it collects faeces or urine as it leaves the body. Different bags and accessories are available, and the most suitable option depends on your stoma, skin, output and individual needs.

Your stoma nurse will normally help you learn how to empty, change and care for your pouch. You do not need to know everything immediately.

A few basics beginners often learn first:

How to empty the bag safely
How and when to change the pouch
How to clean and protect the skin around the stoma
How to check that the pouch is fitted securely
Which supplies you need to keep at home
What to do if you experience leakage or skin irritation
When to contact your stoma nurse or GP

It is completely reasonable to ask your healthcare team to demonstrate something more than once.

What Is Ostomy Surgery Like?

The exact process depends on the type of ostomy and the reason for having surgery.

For example, NHS guidance explains that colostomy surgery involves bringing part of the colon through an opening in the abdomen. Colostomies may be created using open or keyhole surgery, depending on the circumstances.

An ileostomy similarly involves bringing part of the small bowel through an opening in the abdomen.

Before and after surgery, your healthcare team should explain what is happening and give you instructions for caring for your stoma.

If you are preparing for surgery, consider asking your surgeon or stoma nurse:

Will my stoma be temporary or permanent?
Which type of stoma will I have?
Where will it be positioned?
What supplies will I need at home?
Who should I contact if I have a problem?
What changes should I report to my stoma nurse or GP?

Writing your questions down before an appointment can help, especially when there is a lot of information to take in.

Your First Weeks With a Stoma

The first few weeks can involve a learning curve. You may be getting used to emptying your pouch, understanding your stoma’s routine and figuring out which products work best for you.

You might also have emotional reactions that you did not expect. Feeling embarrassed, frustrated, uncertain or simply tired of thinking about stoma care does not mean you are coping badly.

Give yourself time.

Your stoma nurse can help with practical concerns such as pouch fitting and skin care, while support organisations can provide another source of reassurance. Colostomy UK offers information and support for people living with stomas and their families, while IA (Ileostomy & Internal Pouch Association) supports people living with an ileostomy or internal pouch.

Does Having an Ostomy Change Everyday Life?

An ostomy does change how you manage bodily waste, but it does not mean that every part of everyday life has to stop.

Many people gradually develop routines that make stoma care feel much less noticeable. You may eventually become more comfortable planning what supplies to carry, managing your pouch and recognising what works for your body.

If you have concerns about eating, exercise, travelling, work, clothing or other activities, discuss them with your stoma nurse. Advice can be individual, particularly during recovery.

Most importantly, you do not have to figure everything out on your own.

When Should You Ask for Help?

Your stoma nurse, GP or surgical team should be your first point of contact for concerns about your individual health.

Seek professional advice if you notice a change that worries you, particularly if your stoma looks significantly different from what your healthcare team has told you to expect, or if you are experiencing persistent leakage, skin problems, pain or other concerning symptoms.

Do not feel that a question is too small to ask. Stoma nurses deal with these concerns every day.

A New Stoma Is a New Skill — Not a Personal Failure

If you have recently had ostomy surgery, you may still be adjusting to the idea of having a stoma. It can take time to become comfortable with the practical side of things, and there is no fixed timetable for feeling confident.

The most important thing to remember is that your stoma is part of a medical solution designed to help your body function after surgery or illness. You are still the same person, with the same interests, relationships and plans.

Start with the basics. Learn one task at a time. Ask your stoma nurse questions whenever you need to.
